Frequently asked questions
Do colors have commonly accepted names?
Some shades do – there are about 140 in CSS (crimson, teal, coral), in the RAL system names are tied to numbers on a paint fan deck, in Pantone to a printing catalog. The same name means a different shade in different systems, so for accurate color handoff between a designer, a printer and the layout, a code is more reliable than a name.
How can text and background contrast on a site be checked?
The contrast between text and background is not just a matter of looks but an accessibility requirement: colors too close in lightness are hard to read for people with reduced vision and on screens in bright sunlight. When choosing a "text and background" pair, it is worth checking not only the hue but the difference in lightness – the third value in HSL.
Why does a color look different on screen and after printing?
RGB describes color as the light a screen emits, mixing red, green and blue rays. CMYK describes color as ink on paper, which instead absorbs part of the spectrum. The range of colors available in RGB is wider than the range that can physically be produced by mixing real printing inks – so some bright screen colors have no exact match in print at all, and the converter shows the closest possible approximation, not an exact match. That is why converting a color from RGB to CMYK always remains an approximation, and the final shade on paper further depends on the printer and the type of paper.
What do the letters in HSL mean?
H is hue, it sets the color itself on a wheel from 0 to 360 degrees. S is saturation, in percent. L is lightness, in percent: 0% gives black, 100% gives white, regardless of the first two values.
Can a color be entered by name instead of a code?
A limited set of named colors (such as red, white) is supported by the CSS standard, but for an accurate, predictable result it is more reliable to enter a specific code – HEX or RGB.
Does the same HEX code give the same color in different graphics editors?
The code is identical, but the actual appearance depends on the monitor's calibration and color profile – on different screens the same HEX can look slightly warmer or cooler.
Does the tool build a ready-made palette automatically?
No, the form accepts and converts a single color – it does not automatically build a ready-made named color palette and does not pick a contrasting pair. To grab an exact color from an image instead of typing a code by hand, the color picker helps.
Enter a color in any format – the tool converts it into the other common systems: HEX, RGB, HSL, CMYK and others. Enter the value in the "Color" field and press "Convert".
Ways of writing a color
| Format | Example | Where it is used |
|---|---|---|
| HEX | #3A7BD5 | CSS, website layout |
| RGB | rgb(58, 123, 213) | CSS, programming, working with transparency (RGBA) |
| HSL | hsl(214, 64%, 53%) | Picking shades of one hue by lightness and saturation |
| CMYK | 73%, 42%, 0%, 16% | Printing, where inks are mixed rather than light |
HEX, RGB and HSL describe the light of a screen and convert into each other without loss. CMYK works differently – it is about ink on paper, so a conversion from RGB to CMYK is always approximate: the exact printed color also depends on the printer, the paper and the calibration.
How to pick a color combination
The color entered is a starting point, not a ready-made palette. The classic approach to combinations is built on the color wheel:
- Monochromatic combination – one hue, different lightness and saturation. In HSL it is enough to change just the second and third values, leaving the first one (the hue) unchanged.
- Contrasting combination – colors from opposite sides of the wheel, for accents and high visibility.
- Analogous combination – colors next to each other on the wheel, for a calm, cohesive palette.
